GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 224,744, dated February 17, 1880.

Application filed November 15, 1519.

To all whom it may concern:

Be it known that I, CHARLES L. Tluvrs, of Minneapolis, in the county of Hcnneprn and Statcoi Minnesota, have invented cert-nun Improvements in Grain Binding Machines, of which the following is n specification.

My invention relates to that class of grambinding machines in which elevating or raking mechanism delivers a continuous stream of grain, which requires to be separated into proper quantities to form bundles. In thcde vision of the grain it is necessary that each bundle shall be divided cleanly and wholly from the loose grain.

It is to accomplish this result and present the grain properly to the binding-arm, and at the same time render the machine simple in construction. that my invention is designed; and to this end it consists in a reciprocating carrier and divider arranged between the grain elevating or delivering mechanism and the binding-arm in such manner that it receives the loose gmin from the elevator and carries the same forward in proper quantities to the binder-arm, holding back the loose incoming grain at the same time.

The invention also consists in various peculiiu'ities and details of construction.

My improvement may be modified and changed in form; but the drawings represent.

the construction which is preferred. As the band-fastening devices, spools, take-up, and tension devices may he of on ordinary construction, and form no part 0 my invention, they are omitted.

Figure 1 represents a perspective view of my improved machine with the carrier in position to receive the loose grain; Fig. 2, a similar view of the parts in position for the binder-arm to nap the groin; Fig 3, a vertical eross-sect1on, showing the binder-arm in the act of binding the bundle.

A represents the grain table or receiver. and B the elevating or conveying aprons, having their ends arranged to deliver the grain some distance above the table. 0 represents the vertically-vibrating binder-arm, mounted on a. rock-shaft, D, in a fixed standard, E overgouging the outer side of the grainhie, as

own.

The binder arm may he of any suitable form and actuated by any suitable mechanism, but should in every instance be located at such distance from the elevator or other delivering mechanism that the latter will not deliver the grain within its vouch.

F represents my dividing-boon}, mounted edgewiasc upon the table in the direction of the length of the grain, and free to move to and fro between the binderou'm and elevator. At its upper ell n the board is secured to one edge of a flexib c horizontal apron, G, which has its opposite edge attached to u take-up roll, H,locnted beneath the end of the elevatols.

The roll will be provided with a spring, as shown in the drawings, or connected with actuating mechanism to cause it to keep the apron taut and wind it up as the board F recedes toward the elevator.

The binder-arm and the dividing-board are connected with mechanism which causes the board to advance from the elevators to a point close to the path of the binder-arm before the latter-descends, and then causes ittomovc back again after the binder-nun has grasped the rel.

This connecting mechanism may be of any suitable character but in the drawings the hinder-arm shaft 15 provided with a slotted am, I, acted upon by a stud on a vibratin lever, J, which latter has its lower end slotte and driven by n crank, K. This crank acts upon an arm, L, attached to n rock-shaft, M, which is provided also with two arms, N con nected to arms on the end of the board I, so that the sin 1e crank serves to impart motion both to the rd and the binder-lino.

The band-tunnelling devices may be of any approved style located beneath the binder-arm.

When the binder-nun is in its elevated position the d ividin g-board stands directly below the end of th elevator with the apron wound upon the roll, as shown in Fig. I. The loose groin falls from the elevator to the table in front of the board F, and when a sul'fieieut amount has accumulated toform a bundle the board moves forward and carries the some within reach of the binder-arm at the same time extending the apron, whi serves as a we bridge in rear of the board to receive and suntain the loose grain falling from the elevator and prevent the some from falling behind the board. After the binder-arm has seized the grain in front of the board the latter recedes, and the accumulated grain falls in advance of the boa-rd and is carried by its next advance to the bindingnrm, the grain accumulating mean while upon the apron for the next bundle, and so on repeatedly. In this manner each bundle is separated perfectly from the flowing stream, and this without the use of ninoveble binding mechanism or otherexpensive mechanism usuall y employed to eflect the separation and delivery of the grain from the elevator to the binder-arm.

The form of the board and manner of mounting and opemting the some may be modified.

The apron may be made of nnysuitnble matcrinl, or in place of the apron a series of straps, flexible rods, or pivoted and crossed rods may be used, provided the; serve, like the apron, as a horizontal seli adjnsting bridge between the dividing-board and the elevatorirame.

In order to prevent the grain from the elevator from working back under the lower roll, I place a rounding or semicircular breast in front oi and below the lower roll, as shown. The grain passing over the breast lodges there under and is prevented from working upward.

I am aware that slats and other devices have been employed to throw the grain away from the roll; but 1 find by practical tests that the breast, as shown, is decidedly the best and most efi'ect-ivc.

The construction of the binder-arm and the devices monn ted thereon constitutes no part of the present invention, but is embmeed in another application benring date prior hereto.

Having thus described my invention, what I claim isr 1. Thecombinatiouofthebinder-ermmounted in fixed supports, the sliding divider, the extensible apron or bridge, and the elevotor 2. The combination of u'binder-arm, an elevated grain conveyer or e jjvntor, and an alterlnedlate reciprocating ividcr, and an extensible horizontal bridge to support. the inflowing grain during the advance of the divider. 4

3. The combination of the elevator or conveyor, the token! roll, the apron, the dividerbonrd, and u bin er-arm.

4. The combination of a grain -delivering mechanism, menus for delivering the grain from the conveyor to the binder-arm, and an extennible'bridge or apron to sustain the flowin grain during the advance of the conveying devices.

5. The combination, in a. grain-binder, of the spring-driven roll, the apron, and the upright divider-hoard.

6. In combination with the elevator-apron, the breast-piece, constructed and arranged as shown.

7. In combination with the reciprocating dirider, the rock-shaft having three arms, and the crank arranged to actuate the same.

8. The combination of a grain -delivering mechnnism a binder-arm located at a distance therefrom, and an intermediate divider and carrier, arranged to more bodily to and fro in a horizontal direction and sustain the inflowing grain as the bundle is carried to the binder-arm.
